LAWRENCEVILLE - A Lawrenceville police officer suffered a fractured hand Friday when another car struck and totaled his police cruiser while he was en route to a separate traffic accident, police said.

Lawrenceville police Sgt. Ryan Morgan said Monday the officer was struck by a car driven by a lost motorist at the intersection of Gwinnett Place and U.S. Highway 29 as the officer was responding to a motor vehicle accident with the report of a person trapped.

The officer, whose cruiser was severely damaged, suffered a broken hand, Morgan said. The driver of the other car, an elderly woman, was unharmed.

As the officer approached the intersection on Gwinnett Place with lights and sirens at 3:36 p.m., Morgan said, a car driven by a lost motorist in the center lane turned left and T-boned the police car, causing it to careen into a parked vehicle at a nearby business.

The woman was cited for two failure to yield violations, including failure to yield to an emergency vehicle, Morgan said.
